Just a small modification I made of the idle fix plugin. Instead of having idle blocked only on certain conditions, in this one it will be fixed for ever. The only way to go idle is to stay afk and have the server put you in it.
I made this because there is just so much exploits that can be done with it, that the original plugin just was not enough.
I am not posting the source code because I lost it long time ago, but I still use this compiled version. So just wanted to share for anyone who would like to use it.
